Fusion is multiple decades ahead of us still, even with more funding, but we need to take action this decade if we want to have an impact on global warming.

Fusion is unfortunately not going to help here.

There will never be one solitary erg of commercially viable energy from Tokamak fusion. Costs are already known to be sky-high, many many times that of e.g. current nuke, which has always been quite a lot more expensive than all the alternatives.

Current government-funded fusion research is a jobs program for hot-neutron physicists to maintain a population to draw on for weapons work. It actually steals all the funding from what could be viable projects.

If we had put the money in renewables we almost certainly would have solved the problems by now.

My dad studied physics in the 60ies when fusion was just 20 years away.

Some Dutch engineers did a lot of pioneering work with wind turbines in the 1970s and nobody took it seriously.
